Having added the "related searches" feature nearly a decade ago, Search today is able to do much more than it was originally catered towards.
Google has been quietly improving its Search app by working on three different features that make it easier to learn about the topics that you have an interest in learning more about.
Now when you search for a specific topic - let's say you want to find out more information about the historical figure, Ivar the Boneless - the results will come to you as a Feature Snippet - an algorithmically generate box that appears at the top of the page when you search.
While the changes are small and revolve mostly around relevant and related searches, Google aims to constant improve Search without compromising on the core functionality. That's to say that it showcases "featured snippets" which give a summary of topics, related content to search results, and suggested topics. If you're searching for info about skiing, you'll see related searches for sports such as snowboarding directly inside the result. While getting you accurate answers to your questions is still important to Google, getting this information to you in a more timely fashion is also something that the search giant is constantly working on. The similar Knowledge Panels will also show related content now. If you begin searching for multiple soccer players in succession, Google will serve you with related soccer players to assist you in your search.
Last but not least, Google has improved the Search function so now when you search for two related topics, you'll find additional recommendation links at the top of the search page. It's essentially adding more context to search suggestions.
